Project Description

Two stage shock mount and vibration isolator for severe dynamic environments such as shipboard and ground vehicles.

Barry 2K-Series mounts offer the advantage of superior vibration and shock protection for a wide range of loads in a single compact unit. These isolators are ideal for isolating naval sonar equipment, ship board electronics and communications.
